TO ALL WHOM IT MAY CONCERN;

Be it known that we, R. O. CODDING and G. W. PRINGLE, of Coddingvillainthe county of Medina, and State of Ohio, have invented a new andimproved-Wagon-Bral e; and we do hereby declare that the following is afull, clear, and exact description thereof, reference being had to theaccompanying drawings, forming part of this specification.

Our invention has for its'objceta brake applied to the front wheels of awagon and other vehicles in descending a hill, to relieve the team fromthe pressure of the load. It consists in attaching the neck-yoke to theupper end o't'o vertical lever pivoted a; little below its centre to theend of the pole or tongue. The lower end of the lever is connected by ajoint to the end of a bifurcated bar that extends back and connects withtwo arms which are attached to the brake-bar or shaft. 7

It also consists in providing anti-friction ratchet-rollers whichoperate upon the periphery of the two front wheel's of a wagon, allbeing constructed in such a manner as to. be automatic in its operation.

To enable others skilled in the art to make and use our invention, wewill proceed to describe its construetion and operation.

Figure 1 is a top plan view of a wagon with our improved brake attached.

Figure 2 is a longitudinal vertical sectional elevation of the same,taken from the line m x. Letters of like name and kind refer to likeparts in each of the figures.

A may represent a,wagon of common or ordinary construction, adescription of which is deemed unneeesf sary, as we claim no part of itas our invention. p

B B are two wheels whichruu upon the forward axlc-tree, G. D D aretwo-hounds or braces secured to the axle-tree C.

E is the pole or tongue, secured to the hounds or braces D D by meansofa long pivot-bolt that passes through the braces F F, and hounds D D,so that the end of the tongue may be elevatedv or lowered.

G is the neck-yoke attached in the centre to the upper end of a verticallever, H, that is pivoted to the forward end 0t the tongue or pole E, bya pivot-bolt, a.

The lower end 'of the'said leven H is connected at Yto a bifurcated rodor bar, M, that extendsi'backward and connects 'to two arms, a c, whichare attached and extend downward from the brake-shaft I.

The brake-shaft I-is secured and works in eyes which are secured to across-bar, J, the said cross-bar J being secured to the top of the.braces or hounds D D. I The. brake-bar qr shaftI lies immediately overand across the hounds, until itapproaches the two front wheels, B, whenit rises by an angle, so as to form a sort of crankshaft, upon the outerends of which are the brake-blocks, K K, which work upon the ends of thebar -or shaft I. In these blocks, K K, are ratchet-rollers, n it, whichare also secured in their position by means of the arm, or the end ofthe brake-bar or shaft 1, passing through this centre.

w w are steel-spring pawls secured to the upper end of the block, whichworks in the ratehets n n, so as to prevent the wheels at n from turningwhen brought in contact with the wheels-of the carriage, but will allowthe wheels to back without friction, as the ratchet-wheels will turnround by the friction produced upon them by the wheels B B.

L isa curved steel spring, one end of which is secured to the end of thetongue, while the other end acts against the neck-yoke and upper end ofthe pivoted lever I-Lso as to prevent the brakes acting against thewheels when not desired.

The operation of our improved brake is automatic and reliable. Whendescending a hill, and the wagon begins to press upon the team, thetongue moves forward, which draws the neck-yoke back, which throws thelower end of the lever forward, which draws with it the rod or bar M,that is connected to the brake-bar or shaft I in such a manner as tobring the friction-wheels at n hard upon the wheels'B B. i I

When the pressure upon the team ceases by the action of the springs L,the neck-yoke is thrown'forward, and the brakesor wheels at n becomedisengaged from the wheels.

Having thus described our invention, what we claim as new, and desire tosecure by Letters Patent, is

1. The pivoted lover-H, and rod or bar ill, operating the brake-baror-shatt I, and ratchet-wheels a a, sub

stantially as herein shownnud described, and forthc purposes set forth2. We claim the ratchet-wheels n n, operating silbstantially as shownand described, in combination with the brake-bar or shaft I, as and forthe purposes set forth.

. 3. We also claim the spring L, and neck-yoke G, in combination withthe pole or tongue E, substantially as shown and described. I
